The spider Metacyrba taeniola or commonly known as the black spider is a spider that comes from the kingdom animalia and belongs to the class Arachnida to the category Salticidae. In my area the spider is often referred to as the black spider, that's because the color is very black and dense. This spider still has many other species to spread throughout the world, but many of them live in forest areas or humid places.
This spider has the smallest size compared to other species and this is its shape when mature. They do not live like other spiders, which are like making their webs because these spiders can be preyed upon by any insect and even become a fugitive or favorite food for other insects so they only live by hiding.
Meanwhile, this spider can only prey on mosquitoes by sucking blood on the mosquito's body until the mosquito dies. Here are some pictures of the spider.
